Maybe 56x56 chips can be done quite easily today with 9um pixels, using existing tech? Would be a nice 39 megapixel fat pixel back! Problem is that it would be a huge risk for Hasselblad to test this market, and I don't think they are in the position to take such a risk...

The Fotodiox uses the NEX 7 Shutter. you only need the aperture and focus to be working on the lens.IF you can find a 40mm Hassy lens with a dead , but open shutter and a working iris you have a deal that will work just fine on the Fotodiox Rhino

I've been saying this here and there, but I'm much more interested & looking forward to a MetaBones SpeedBooster for V-mount lenses.

With the same ~0.7x reducing factor of the current ones (FF -> APS-C) but built larger for V lenses, we can have an "effective" full-frame square MF camera with a "crop" square MFDB, like CFV, privded somebody designs a nice "body" to be placed between everything.

The setup would look something like this:

||CFV-16||"BODY"w/FS&WLF||SpeedBooster-V||V-Lens

Since the SpeedBooster requires a much shorter deistance between its rear element and the plane of focus, extant V bodies won't work, meaning somebody would have to design & make it. I still think it's more likely that that would happen than somebody give us a 56x56mm sensor :p
